The chemical constituents were isolated and purified by column chromatography with silica gel, ODS, and Sephadex LH-20. Their structures were elucidated by IR, MS, and NMR. Ten compounds were obtained and identified as caerudelphinine A(1), lycoctonine(2), talitine B(3), talitine A(4), talitine C(5), tatsienine-V(6), d-magnoflorine(7), 2-trimethyl-ammonio-3-(3-indolyl) propionate(8), vakhmatine(9), and delatisine(10). Compound 1 was a new lycoctonine-type C19-diterpenoid alkaloid, and compounds 4-10 were isolated from this plant for the first time.展开更多
